I just flagged an answer
as spam with a custom flag, but I'm having second thoughts.
The answer strikes me as a little rude, and there's an unnecessary link to what I'm guessing is a personal site.
I was tempted to just edit out the snark and self promotion, but I've heard that spam should be flagged and not edited, so moderators have an easier time spotting it.
I know that there are similar questions, but they don't seem to have a really conclusive answer.
What is the protocol here?
